and none of what you posted has anything to do with what we are talking about when it comes to EME or DRM

HBO does not need either to protect me from selling Copies of their content on iTunes.

EME and DRM is about preventing users from utilizing their rights under copyright law to format shift, time shift or consume content they paid for on the devices they desire, instead Hollywood wants to be able to charge the consumer no only for access to the content, but seperatly for each device, each view, each access, and be able to control when and where they view said content preventing users from view their content if they happen to travel internationally, or buy a device not blessed by Hollywood

none of which is allowed under Copyright law directly, but because of the provisions in DMCA preventing breaking of DRM they have illegitimately gained these rights and are using it to violate consumers fair use rights wholesale
